f ,i-NTERCHANGEAZBLE HEEL.

To all whom it may concern Be it known that I, ERNEST, A. WINDSOR, a subject'of the King of Great Britain, residing at Port jHuron, in the county of St. Clair and State of Michigan, have invented certain new and useful Improvements in,

whereby a plurality of different style heels may be used in connection with one shoe.

A further object of the invention is to provide simple andreliable means for detachably securing a cap or tip to the lower end of the heel.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a side elevatlon of a heel em bodying my invention, showing the same attached to a shoe,

Fig. 2 is a vertical longitudinal section through the same,

Fig. 3 is a plan view of the heel,

Fig. 4: is a detail section taken on line 4-4 of Fig. 1,

Fig. 5 is a perspective view of an attaching plate of a heel,

Fig. 6 isa plan view ofthe cap or tip for the heel, p

Fig. 7 is a transverse section taken on line 7-7 of Fig. 6, and

Fig. 8 is a perspective view or" the cap attaching plate.

In the drawings, the numeral 5 designates a shoe, having a sole 6 extending rearwardly into a heel portion 7 This heel portion has an opening 8.

The numeral 9 designates a detachable heel, of any suitable shape or height. The same is shown as a French or high heel, but it may be any other form of heel, such as a Cuban heel.

The heel 9 is preferably formed of alumi- 1 Specification of Letters Patent.

num, and its upper portion'is cored out, providing a chamber 10, having recessesor notches 11, in the opposite ends thereof, as

shown more clearly in Fig. 3. The upper end of this heel is serrated or milled, forming teeth or grips 12, to frictionally'engage with the heel portion 7.

The notches 11 are adapted to receive the ends of a heel attaching. plate 13, which may be formed of steel, brass or the like, and prevent the turning movement of the heel. The attaching plate 13 is secured tothe lower surface of the heel portion ,7 byflat-headed bolts 14, as shown. The attaching plate 13 is provided with a recess or chamber 15, de-

pending therefrom, in registration with the opening 8., and apertured at 16.

-The numeral 17 designates a connectlng pin, the lower end of which is screw-threadt ed for connection within a screw-threaded recess 18, while its upper end projects through the aperture 16 to enter the recess 15, and engages a nut 19, having grooves 20. This nut is disposed within the recess 15 and does not project above the heel portion 7.

The numeral 21 designates a cap or tip for the heel, formed of leather or rubber, and having upon its upper side, a flange 22, provided with a groove 23, and this cap hasfa central opening 24:, as shown.

The numeral 25 designates a ing plate, adapted for insertion within the groove 23, and having portions 26 which are milled or serrated, and a central upwardly bulged chamber 27, with an aperture 28.

The forward end of the plate 25is bent upwardly in a flange 29, to prevent dirt passing inwardly between the cap. and heel. I

The numeral 30 designates a connecting pin, extending through a cored portion or chamber 31, with its upper end screw-threaded into an opening 32. The lower end 33 is "cap attach a screw-threaded and extends through an aperture 28, to engage nut 34:, having grooves 35. r The numeral 36 designates a wrench, hav

ing projections 37, to enterthe grooves of,

the .nuts 19 and 34, whereby either the heel 1 may be removed fro'm'the shoe, or the cap from the heel.

It is to be understood that the form of my invention herewith shown and described is size, and arrangement of parts may be. re-

sorted to without departing from the spirit of my invention, or the scope of the sub joined claim.

Having thus described my invention, I claim:

A molded shoe heel cored in its top and bottom to provide outwardly opening chambers, oppositely disposed pins secured in the intermediate portion of the heel separating 10 the top and bottom chambers and extending through the latter and threaded at their outer ends, plates extending over therespective chambers and having inwardly depressed centrally apertured portions to receive the outer threaded ends of the respective pins, and nuts threaded on the outer ends of the pins and disposed in the depressed portions of the respective plates.

In testimony whereof I aflix my signature in presence of two witnesses.
